Docker Hub image pushes on your phone
July 23, 2026 · 3 min read
The moment your CI pushes a new image to Docker Hub is the moment deployments become possible – and the moment you want to know about. Docker Hub's built-in webhooks make that a two-minute setup.
Setup
- Create an endpoint in the Webhooky app (Android / iOS) – “Docker Hub”, sound
coin, default text “New image pushed”. - On Docker Hub open your repository → Webhooks tab → name it, paste your endpoint URL, save.
From now on every docker push to that repository triggers a push notification. The payload (push_data.tag, repository.repo_name) carries no title/message fields, so your endpoint's texts appear – one endpoint per repository keeps tags distinguishable.
What it's good for
- CI confirmation: the audible “image is out” after a long build, without watching the pipeline.
- Team awareness: hear when a colleague publishes a new version of a shared base image.
- Deploy triggers: if a watchtower-style setup auto-pulls new tags, this push tells you a rollout just started.
Note: Docker Hub only fires webhooks for your own repositories – for watching third-party images, pair the pull with your own container monitoring. The CI push itself can also notify with custom texts straight from the pipeline: GitHub Actions, GitLab CI.
